Generative Orchestration shows unmasked draft before my PII topic replaces it — how to prevent?

Hi all 👋

I’m on Copilot Studio with Generative Orchestration ON. I use a custom topic triggered by “AI response generated” to PII-mask the model’s draft and replace it.

Issue

After “Fetching knowledge,” the unmasked draft briefly appears, then my masked message replaces it. I need to prevent any unmasked text from showing at all.

What I’ve tried:

In the custom topic:
Run a prompt (PII) with input = System.Response.FormattedText → returns sanitizedContent.
Send only sanitizedContent.
System.ContinueResponse = false (tested as first and last step).
With and without Power Automate (when used, returns values only, no user message).
Also tried Search knowledge sources inside the topic (mask then send).

How can I stop the generative draft from streaming so only my masked message is shown?

Is there a pattern to guarantee zero exposure of unmasked content in Generative mode?

Thanks a lot in advance! 🙏

hello

this happen to me when the conversationnal boosting "think" the answer is not enough or out of bound.

You could disable it by going to Topics->System->conversationnal boosting and disable. Then you will have few error inside the agent because few other system topics use it, correct / remove the part and then go.

This system topic "conversationnal boosting" is a relic of the past when GenAI was not default mode (the classic one was). it was very very usefull at this time.

With gen AI orchestration, knolwedge are triggered automatically after topics, so conversationnal boosting is not needed anymore in real life agent, it's just a "safe net" to help.

most of the time, it solve my problem.

If not : check the general knowledge if it's disable or enable (could influence) and in gen AI settings, you could check default AI model and change (it could influence too)

hope this help :) if yes please check the answer button to make the post green, it's important for the community and search engine :)
